The thing is: (and is this only my observation after years of gazing at him) that this new bulk in the upper body looks a bit awkward on him because he has a long neck and a smaller head. And his legs remain shapely and slim. Okay, shoot me; I know he's our boy but it's something that bothers me just a bit. Maybe that's why I like his hair long.
On the upside, this configuration allows him to rock a tailored suit.
Rafa does have bigger muscles but he's bigger overall with legs like tree trunks. The guy is one solid mass.
